		5.3 Host Commands
Bits 12-8:	In the case of Device 1 (slave drive), a valid value is set.
	Bit 12:	Reserved
	Bit 11:	'1' = Device asserts PDIAG-.
	Bit 10, 9:	Method for deciding the device No. of Device 1.
		'00' = Reserved
		'01' = Using a jumper.
		'10' = Using the CSEL signal.
		'11' = Other method.
	Bit 8:	= '1' (In the case of device 1)
Bits 7-0:	In the case of Device 0 (master drive), a valid value is set.
	Bit 7:	Reserved
	Bit 6:	'1' = Device 1 is selected, Device 0 responds.
	Bit 5:	'1' = Device 0, assertion of DASP- was detected.
	Bit 4:	'1' = Device 0, assertion of PDIAG- was detected.
	Bit 3:	'1' = Device 0, an error was not detected in the self-
		diagnosis.
	Bit 2, 1:	Method for deciding the device No. of Device 0.
		'00' = Reserved
		'01' = Using a jumper.
		'10' = Using the CSEL signal.
		'11' = Other method.
	Bit 0:	'1'= (In the case of device 0)

*21 WORD 94

Bit 15-8: X'FE' Recommended acoustic management value.

Bit 7-0: X'XX' Current set value.

FE-C0: Performance mode

BF-80: Acoustic mode

00:Acoustic management is unused it. (It is same as "FE-CO")

*22 WORD 100-103

When "48 bit LBA" of the option (customize) is supported, same number of LBA as WORD 60-61 is displayed.
